SYSTEM F CONSTRUCTION WITH BETON-STRENGTHENED BY METAL.

SPECIFLCATON forming part of Letters Patent No. 693966, dated. February 25, 1902.

Application tiled May 14, 1901.

To all whom t may concern: Beit known that I, HEINRICH HENKEL, a citizen of Germany, and a resident of Rue du Gouvernement Provisoire, Brussels,.Bel 5 giu m, have invented acertain new and useful System of Construction with Beton Strengthened by Metal, of which the following is a specification.

The present patent application has for its object a new system of construction with beton strengthened by metal, by which structures-of all kinds can be built with as small as possible an amount of material, while insuring great stability. By this method of construction the time required for execution of the work is greatly lessened, as well as the preparatory work required for other systems. The new method is equally applicable to floors, reservoirs, walls, quays, &c.-'-that is to say, to all kinds of structures.

Figures l and 2 of the annexed drawings show by way of example the application of the system to the construction of a floor. Fig. 2a is a perspective View like Fig. 2 of a different arrangement of the parts; Figs. 3 to 6, the application of the same method to the construction of a gasometer-tank. In the first example the structure is horizontal, while in the second it is cylindrical.

In the case of the iioor (shown in Figs. `l, 2, and 2a) two girders a are placed the one some distance above the otherand are connected at intervals by clips b. The girders are quite buried in beton, forming a beam fg h i, in which the upper girder is subject to compression and the lower to tension, the neutral axis being between the girders a a in the mass of beton. The panels y 'y are made of thinner beton and may extend over great space, owing to the special arrangement of the strengthening metal .e of helicallytwisted bars of ilat iron extending in one piece withoutabreak overthree,four,or iive panels, passing for this purpose through between the girders a a in the neutral axis of the beam. Thus the panels between the beams are not separated from each other, vas in ordinary structures,4 but, on the contrary, are intimately connected to one another, so that the 5o floor may be considered to be in one piece.

Serial No. v60,13 1- (No model.)

Furthermore, theirons ,ez pass to and fro several times through the same set of panels, being for this purpose at each of the end beams bent back upon themselves several times, as shown at Z. On the other hand, the adjacent irons are connected to each other by passing through loops Z, so formed as to constitute continuous strengthening metal over the whole extent of the iioor. (See Fig. 2.) This construction of floor presents a great advantage on account of the ease with which it can be executed,as the scaffold-planks can be hooked to the lower girder a without requiring other supports.

The application of the system to the construction of reservoirs (shown in Figs. 3 to 6) presents the following specialties: The mode of construction is absolutely the same, comprising, like the former, the combination of sets of double girders and helically-twisted 7o strengthening-bars of flatiron, only the structure is vertical instead of horizontal. As the iioor is divided into a number of panels be tween beams, so the reservoir consists of a set of vertical curved panels between similar vertical supports. The girders u fu, correspending to a a4 in the former structure, are buried vertically in beton in the foundation and consolidated by anchoring-stays w w. There are then applied between the girders o n the casing-planks for the formation of the beton, instead of its being necessary, as is usually the case, a complete mold extending from the wall that is to be raised tothe center of the apparatus and completely filling the reservoir-space, the mold for the circular part being composed in the most cheap and simple manner by the vertical girders u n and the planks which connect them. The sets of supports c buried in the beton being externally buttressed by the stays of the snpports w, and the beton panels possessing, as above, the same system of metal strengthening helical bars fr, singleV or double, arranged horizontally in the beton .and continuously connected together, as in the case of the floor, it results that the thickness of the panels or circular wall can be considerably reduced while still maintaining a structure as solid as the ordinary heavy structures, *As has roo been already stated, this arrangement is therefore the same as the former, except that the structure is vertical instead of horizontal.

The process can likewise be applied to the construction of quay-Walls of less thickness than that usually adopted, While possessing the same stability, and generally to all structures.

Obviously the system is capable of nu merous practical modifications while still remaining Within the scope of the present invention. Thus Without conlining myself to details of the construction I claim- A new system of construction with beton strengthened by metal comprising the combination of a set of girders arranged in pairs
